I'm trying to upload a background image to my WordPress site, using the Atahualpa theme. Following the instructions, I tried uploading it to /wp-content/themes/atahualpa/images/ but received the message that it had an error uploading.
Repeated, same error.
My question is, how do I upload it to this directory? The current way doesn't seem to allow me to do so, and until I've done that, I can't really set my background. Thanks in advance.
